Tools on top of air conditioner unit

The outside air conditioner unit radiates heat out of your home and into the open air. If something prevents the heat from radiating out, then the unit will not work properly. It can develop ice, break down, and start costing you a whole lot more in utilities than it should. That’s why cleaning the outside unit on your air conditioner is a critical part of air conditioner maintenance. You can get the professionals to do this, or you can do it yourself.

Use this step-by-step guide to clean the outside of your air conditioner unit.

1. Remove Debris

Your first step should be to clear off debris that is on the outside of the unit, like leaves or dirt. You can use a stiff broom to do this, or just a cloth, depending on the debris that has gathered.

2. Remove Fan Cage

To clean the inside of the unit, you will need to remove its outer case or cage. You should be able to remove it by removing the fasteners, usually screws, from the cage and then carefully lifting it off. Either by hand or with a wet shop vacuum, you can clear off any immediately obvious debris that has gathered inside of the fan cage. Don’t use a dry vacuum, as the debris may be wet.

3. Clean the Fins

The fan unit inside of the air conditioner needs to be cleaned either with a wet cloth or with a garden hose. Gently rinse down each fan to remove the dust and dirt on the fins. You can also make sure that the fins are straight and bend them back into position if they are not. Just don’t hurt the tubing or the other delicate parts nearby.

4. Clean Evaporator Coil

Now you can locate and remove the evaporator coil cover. This is one of the most important parts of the air conditioner so ensure to work carefully. You need to purchase a no-rinse cleaning solution specifically meant for this purpose. Follow the directions on the spray to clean off the coil.

5. Clean Evaporator Drain

The drain pan under the evaporator coil also needs to be cleaned, especially if it is draining slowly, is clogged, or has developed mold or algae growth. You can clean it out with the wet vacuum you were using earlier.

6. Change Filter

The outdoor unit on your air conditioner has a filter. It’s wise to change the filter (or clean it out if it is reusable) while you are cleaning the rest of the air conditioner unit.

7. Restore the Cage

Be sure to put all covers and cages back before you turn the air conditioner back on.
